It is clear from much work by several groups on many hydrocarbons (see, for example, Lit. Cited) that isotopic exchange between deuterium and hydrocarbons on metal catalysts involves a number of processes. The turnover frequency per surface metal atom for the formation of all exchanged species plus the isotopic distribution pattern (the relative yields of d/sub 1/, d/sub 2/, d/sub 3/...) have a large information content from which one may hope to extract important mechanistic information. The fundamental processes in alkane exchange are: dissociative adsorption of hydrogen, dissociative adsorption and associative desorption of alkane, and interconversion of monoadsorbed and 1,2-diadsorbed alkane. These are illustrated for an ethyl group.
